Find out more about CVE-2015-0239 from the MITRE CVE dictionary dictionary and NIST NVD.
Statement
This issue did not affect the kvm packages as shipped with Red Hat Enterprise Linux 5 as they lack support for sysenter instruction emulation.
This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7. A future update may address this issue.
Please note that the Red Hat Enterprise Linux with KVM certified guest operating
systems do initialize the SYSENTER MSRs and are thus not vulnerable to
this issue when running on KVM hypervisor.
